Joint Radio-Frequency/Baseband Self-Interference Cancellation Methods and Systems |
摘要 |
System, method, and apparatus embodiments are provided for a joint radio-frequency/baseband self-interference reduction system to obtain an intended signal in a full-duplex capable transceiver. In an embodiment, a method for reducing self-interference (SI) in a full-duplex capable transceiver includes obtaining an adjusted signal, wherein the adjusted signal is a difference signal between a received signal in an analog domain and an estimated SI, wherein the estimated SI is estimated according to an SI received at a receiver during a half-duplex operation; and obtaining an intended signal, wherein the intended signal is a difference signal between the adjusted signal in a digital domain and an estimated residual SI, and wherein the estimated residual SI is an amount of SI remaining in the adjusted signal after removal of the estimated SI from the received signal. |

1. A method for reducing self-interference (SI) in a full-duplex capable transceiver, the method comprising:
obtaining an adjusted signal, wherein the adjusted signal is a difference signal between a received signal in an analog domain and an estimated SI, wherein the estimated SI is estimated according to an SI received at a receiver during a half-duplex operation; and obtaining an intended signal, wherein the intended signal is a difference signal between the adjusted signal in a digital domain and an estimated residual SI, and wherein the estimated residual SI is an amount of SI remaining in the adjusted signal after removal of the estimated SI from the received signal. |
